DEVICEFOR RAISlNG OR LOWERING AWNINGS.

SPECIFICATION forming part f Letters Patent No. 705,744, dated July 29, 1902. Application filed March 31,1902. Serial No. 100,678. (No model.)

Lowering Awnings, of which the following is a specification.

My invention relates to an improvement in means for manipulating awnings; and the object of the invention is to provide the parts of great simplicity, strength, and durability and so located in a housing as to be concealed and yet readily accessible. to operation.

The features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is an end elevation of my improvement with the housing-cap removed. Fig. 2 is a side'elevation of Fig. 1. Fig. 3 is an end view of the housing and cap imposition. Fig. 4 is a front elevation of the housings and projecting parts. Fig. 5 is a'perspective view of the housing-cap.

A representsa wall of a building.

B represents the base of the 'case or housing, which is rigidly anchored to the wall by screw-bolts a. i

0 represents a casing or housing rigidly secured to the base-piece B.

Drepresents the driving-shaft. It is journaled in the base B and the outer side wall of the shell C of the case.

E represents a vertical transmitting-shaft projecting up parallel with the wall of the building, its lower end journaled in the end wall (1 of the casing. The upper end of said shaft journals in the bracket 6, which is securely anchored to the wall of the building.

F represents a bevel-gear on shaft D.

G represents a bevel-gear on the lower end of shaft E.

I represents the roller on which the awningcanvass is wound.

J represents the bevel-gear secured to the end of the roller 1, meshing with and driven by the bevel-gear H.

K represents a ratchet- Wheel secured to L represents a lock-lever pivoted to the up per edge of the casing C. This is provided with a tooth g, adapted to engage serially with the teeth h of the ratchet-wheel. The shape of the teeth 9 and h is such that when the awning-roller is wound up these teeth come into locking engagement and hold the awning from unwinding.

m represents a locking and tripping arm rigidly fixed to the pawllever L. It projects outward through the slot t' of the casing-cap C. The outer end ofthis stem is provided with an eye. Upon'the casing-cap is mounted a rigid car a, likewise having an eye, which when the ratchet-lever L is in engagement with one of the ratchet-teeth It occupies the position shown in Fig. 4. ,,This eye is in juxtaposition with the eye of the ear n, in which position they may be securely locked by the hasp O of an ordinary padlock.

P represents the projecting end of shaft D, squared to receive a crank, so that the said shaft may be turned.

Mode of operation: Suppose the awning to be wound up, but the padlock O removed. If it is now desired to unwind the awning, the attendant applies the crank to the squared head P of the shaft. He then turns the crank toward the winding direction slightly, and he can then easily lift the ratchet-lever L by taking hold of the projecting end and allowing the awning-pole to be unwound, applying sufficient power to the crank to prevent too rapid unwinding, and consequently tearing the awning from-01f the pole. When the awning has been unwound, he releases the pawl-lever L, which maybe locked in this position, if desired. To roll up the awning, the attendant simply turns the crank and the pawl-tooth automatically comes into serial engagement with the ratchet-teeth 77.. When the awning is wound up to the desired position, the lever-stem m can be locked to the car it and the crank removed and the awning secured against accidental unwinding. This locking also prevents mischievous persons from tampering with the fixture.

Several important advantages are obtained by the construction herein described.

As the strains are on the horizontal drivingshafts and the casing is projected from the side wall, it is desirable to have the thrusts on said shaft sustained as much as possible upon the base. The said shaft D is'projected in shown and described.

across the casing and is j ournaled in the base of vertical wall B, which journal is in the plane of the anchor-bolts a. It will be observed that the cap-piece of the casing and the casing have two fastening-flanges, one of which forms a bearing and cap for the shaft E and the other fastening-flange forms the bearing for the shaft D, and the two sections of the case are secured together by bolts passing through said flange-bearings upon each side of the respective shafts, thus making a rigid union of the casings and a firm bearing-support for the shafts, which being at right angles with each other have a tendency to strain the casings at the joints. The con struction therefore is simple, allowing convenient access for the taking down and putting up of awning devices by taking the case apart, which when put together is made strong and durable by the construction here- Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A device for operating awnings consisting of a casing made in two sections, a base B formed integral with one of said sections,

a driving-shaft D journaled to said base and easing provided with a bevel-gear F, a driven shaft journaled in said casing, a bevel-gear on said shaft meshing with the bevel-gear on the driving-shaft, fastening-flanges on said casing which form the bearings of the said shafts, and fastening-bolts fastening through said flanges upon each side of respective shafts, substantially as specified.

2. In a device for operating awnings the combination with a casing adapted to be anchored to the walls of a building, a slotted cap for the casing, adriving-shaft and driven shaft journaled in said casing, a ratchet-gear inclosed within said casing, a pawl lever hinged within the casing and having an arm projecting through said slot in the casingcap, a projection on the casing coincident with the said projecting arm when the parts are in their position, substantially as specified.

In testimony whereof I have hereunto set my hand.
